Run 91

Attempted to move the detectors closer to the beam, and move them in sync with the injection.

Found best position was

Right arm: s by 5 mm, r p in (not moving). No benefits from moving. 10 mm + r p in on sync results in beam clipping during injection. 69.55 mm not moving.

Left arm: s by 5 mm, l p in (in sync with motion). Due to the short beam preparation time, only the trigger out was used as per screenshots below. 23.58 -- 67.90 moving.

Saw spike on leakage current for both detectors on the right arm. Unsure if this because they are being moved, or because they were hit with beam. Leakage current recovered.

Run 92 - acquired data as above.

Rutherford locus more clear on left arm detectors. No clear sign of nuclear reactions signals.
